Description
Technical field
The present invention relates to bridge construction member field, particularly the axle load post of 8 times high of a kind of Reinforced Concrete Bridge shallow pile plate foundation stakes.
Background technology
Fast development along with national economy and Urbanization Construction process, for satisfying the needs of traffic, one-level, Class II highway and speedway also drop in the construction fast, setting up and build also of bridge thereupon increasing rapidly, the executing of bridge built according to what bridge was satisfied in the construction of abutment and held lotus and the stiffness coefficient of stability across the end place, therefore the diameter of bridge pier plays decisive role with the firmness to bridge highly, usually all be to strengthen along with the increase of cushion cap weight, but because the stake footpath of bridge pier can't proportionally increase, in order to satisfy the cushion cap requirement, can only increase the pre-buried degree of depth or the height of stake, this just causes certain difficulty to construction, and causes the waste of material.
Summary of the invention
For overcoming the drawback that exists in the above-mentioned technology, the invention provides the stake of a kind of Reinforced Concrete Bridge shallow pile plate foundation and directly count 8 times high axle load post, when reducing materials, and reach the purpose of effective load-bearing.
For achieving the above object, the technical solution used in the present invention is:
8 times high axle load post is directly counted in the stake of Reinforced Concrete Bridge shallow pile plate foundation, at underground shallow of the circle that is embedded with, and by anti-hanging deck, anti-overarm, the contact beam is fixed, the stake footpath of axle load post be high by 1/8, be provided with and the high contour entity cylinder of stake at axle load post center, stretch out evenly to distribute in the entity cylindrical outer wall and be provided with four and support pilasters, described support pilaster is rectangular structure, height is high identical with stake, on the axle load post, vertically be evenly distributed with nine equidistant cylindrical contact beams, cylindrical contact beam is the annulus rod structure that is combined as a whole with the entity cylinder, and external diameter is identical with axle load stanchion footpath.
Entity cylindrical radius in the described axle load post: support the pilaster length of side: attached wall support column thickness=0.892:0.625:0.358(rice).
Entity cylinder height in the described axle load post: support the pilaster height: each cylindrical contact depth of beam=10:10:0.13(rice).
The invention has the beneficial effects as follows:
1, adopt shallow pilework, produce horizontal thrust and the design considerations of pulling out not according to variable load, utilize the booster action of plate base can increase the capacity value that holds of pile foundation, required pile anchoring hole is shallow, and raw material have also been saved in easy construction.
2, adopt cylindrical solid stake lower plane and support the pilaster lower plane with cylinder with support pilaster and attached wall contacts beam and jointly is substrate, with support column the load-bearing load is shared, and reinforce with the cylindrical pilaster, can satisfy under the condition of load-bearing, reduce to greatest extent the use of material, reach the purpose of economical with materials.
Description of drawings
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is cross-sectional structure figure of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments:
Such as Fig. 1, shown in Figure 2, the axle load post that the stake of Reinforced Concrete Bridge shallow pile plate foundation is 8 times high, be embedded with round shallow 1 underground, and by anti-hanging deck 11, anti-overarm 12, contact beam 13 is fixed, the stake footpath of described axle load post be high by 1/8, be provided with and the high contour entity cylinder 2 of stake at axle load post center, stretch out evenly to distribute at entity cylinder 2 outer walls and be provided with four and support pilasters 3, described support pilaster 3 is rectangular structure, height is high identical with stake, vertically be evenly distributed with nine cylindrical contact beams 4 on the axle load post, cylindrical contact beam 4 is the annulus rod structure that is combined as a whole with entity cylinder 2, and external diameter is identical with axle load stanchion footpath.
Entity cylindrical radius in the described axle load post: support the pilaster length of side: attached wall support column thickness=0.892:0.625:0.358(rice).
Entity cylinder height in the described axle load post: support the pilaster height: each cylindrical contact depth of beam=10:10:0.13(rice).
The below is to solve the load-bearing load as 500 tons, and the single pile base terminal is 30 tons/㎡, and the high 20m of stake is example, carries out required axle load stanchion according to common construction and directly is 2.5m, and institute's materials are 98.2m3.Construct according to the present invention, according to stake end load-bearing 15%, required load-bearing is 75 tons, and then load-bearing area in cross section is 2.5 ㎡, and the entity cylindrical radius that adopts is 0.892m, height 20m, and volume is 50m3; The support column length of side that adopts is 0.625m, and thickness is 0.358m, height 20m, and adopting the cumulative volume of four support columns is 17.9m3; The cylindrical pilaster section area that adopts is that the cross-sectional area of axle load post deducts entity cylindrical cross-section area, and deduct four support column section area, be 1.512 ㎡, according to aforementioned proportion, each cylindrical pilaster height is 0.26m, totally nine cylindrical pilasters are volume required is 3.54m3, constructs according to the present invention therefore that to need material be 71.44m3 to the worker, has saved 27.25% than conventional materials.By 171.6 tons of 71.44m3 meters, bridge plate is wide with 6m, the axle load intercolumniation is that 15m calculates across length, cast-in-situ steel reinforced concrete net lamellar spacing is 0.4m on bridge plate, volume required is 36m3, the thick 0.625m of beam and underground pile anchoring 0.95m are 8.91m3 in addition, 44.91m3 count 108 tons, amount to materials and be about 280 tons, be 500 tons based on holding lotus, it is 220 tons that bridge plate can hold variable load, according to highway bridge and culvert design general specification (JTJ+021-89) regulation, but each 120 tons of car of two way are disregarded impact coefficient, two medium trucks of this wide bridge plate road surface wheeled on the bridge plate.
